we are investigated the anti-inflammatory effects of Safflower and Mother wort Ethanol Complex Extracts(SEC) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of SEC(500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by Safflower and Mother wort Ethanol Complex Extracts were observed in the following. Safflower and Mother wort Ethanol Complex Extracts inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that Safflower and Mother wort Ethanol Complex Extracts exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of Safflower and Mother wort Ethanol Complex Extracts. Therefore, Safflower and Mother wort Ethanol Complex Extracts could be regarded as a potential source of natural anti-inflammatory agents.

This study was carried out to identify the anti-inflammatory effects of Ishige foliacea (I. foliacea) extract on skin using RAW 264.7 cells. The anti-inflammatory effects of I. foliacea extract on RAW 264.7 cells were assessed by cell viability assay, mRNA expressions, and nitric oxide (NO)/prostaglandin E₂ (PGE₂) productions. The anti-inflammatory effects of I. foliacea extract were elucidated by analysis of IL-1α/IL-1β/IL-6/TNFα gene expressions and PGE₂/NO production. Quantitative real-time polymerase chain reaction showed that I. foliacea extract decreased the gene expression levels of iNOS/COX2/IL-1α/IL-1β and IL-6. Furthermore, PGE₂/NO production also revealed that I. foliacea extract exhibited anti-inflammatory properties. These results suggest that I. foliacea extract is an anti-inflammatory compound. It could be a potent cosmeceutical material for anti-inflammatory effects. Further studies on the anti-inflammatory mechanisms of broadleaf extracts are expected to help identify pharmacological mechanisms related to inflammation in addition to cosmeceuticals.

In this study, we selected Gardeniae fructus (GF) as an anti-inflammatory functional material and improved the biological activity of GF through the treatment of ${\beta}$-glucosidase. For the simple evaluation of anti-inflammatory activity, the inhibitory activity of GF extract (GFE) on the production of NO by RAW264.7 cells in the presence of LPS was examined. ${\beta}$-glucosidase originating from Aspergillus niger or Aspergillus fumigatus has effectively improved the anti-inflammatory activity of GFE. The enzyme treatment raised the activity of GFE by more than 10 times. The optimum conditions for the enzyme reaction were at pH 4.6, $45^{\circ}C$, and 20 U/mL for 24 h with agitation. In addition, in vitro production of cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$), COX-2, and the NF-${\kappa}B$ activation of RAW264.7 cells decreased more in the presence of GFE treated with ${\beta}$-glucosidase originating from Aspergillus niger (GFAN) than in the presence of GFE. These results suggest that enzyme-treated GFE might be a potential candidate for natural anti-inflammatory food materials.

Abalone, a marine organism inhabiting the west coast of Korea, has antioxidant and anti-inflammatory effects, and is a resource with potential to be used in various industries such as antibiotic development and cosmetic raw materials. In this study, we chose abalone among various marine lives on the west coast. Antibacterial peptide (AMP) was separated from abalone and its derivative Ab4-7 was identified and its physiological activity was studied. The treatment of Ab4-7 in inflammatory RAW 264.7 to check the anti-inflammatory efficacy nhibited inflammatory cytokines, TLR4, TNF-α, IL-1β, COX-2, and iNOS and increased mRNA manifestation of HO-1, genes related to antioxidants. Based on the strong antioxidant and anti-inflammatory effects of Ab4-7, the effects of Ab4-7 in the inflammatory RAW 264.7 cells were identified through RT-PCR, which regulates the gene Matrix Metalloproteinase (MMPs) that induces a variety of inflammatory skin diseases by engaging in the decomposition of the extrocellular matrix metalloproteinase (ECM). Taken together, it is concluded that Ab4-7 has a powerful anti-inflammatory and antioxidant effect and can be used as a functional material for various inflammatory skin disease treatments by controlling the genes associated with matrix metalloproteinase (MMPs).

The aim of this study was to evaluate the antioxidant activities and anti-inflammatory effects of water and ethanolic extracts from Allium hookeri roots and leaves. Antioxidant activities of Allium hookeri extracts were determined based on various radical scavenging activities using an ESR spectrophotometer, ferric reducing antioxidant power, 2,2'-azinobis-(3-ethybenzothiazoline-6-sulfonic acid) radical scavenging activity, and oxygen radical absorbance capacity assays. In addition, we investigated anti-inflammatory effects of Allium hookeri extract on lipopolysaccharide (LPS)-induced inflammation in RAW264.7 cells. We also explored the effects of extract from Allium hookeri root on suppression of pro-inflammatory mediators such as nitric oxide (NO) and pro-inflammatory cytokines such as IL-6 and TNF-${\alpha}$ against LPS-induced activation of RAW264.7 cells. Our results demonstrated superior antioxidant activity for leaf extract of Allium hookeri compared to extract from root of Allium hookeri. On the other hand, root extract of Allium hookeri showed better anti-inflammatory activity compared to leaf extract. Our study suggests that Allium hookeri extract exhibits strong antioxidant activity and anti-inflammatory effects and can be developed as a potential therapeutic candidate for diseases involving oxidative stress and inflammation.

This study was conducted to develop functional sources of herbal cosmetics for treatment of skin aging and inflammatory disorders using volatile flavor extracts of four different herbal medicinal prescriptions including Cnidium officinale Makino (COM), Angelica gigas Nakai (AGN), Mentha arvense L. (MAL), Artemisiae argyi Folium (AAF), Paeonia lactiflora Pall (PLP), Rehmanniae Radix Preparata (RRP), Scutellaria baicalensis Georgi (SBG), Panax ginseng C.A. Meyer (PGM), Glycyrrhiza uralensis Fisch (GUF). The volatile flavor extracts of four different herbal medicinal prescriptions (HH-1: COM, AGN, PLP, RRP, HH-2: COM, AGN, PLP, RRP, SBG, PGM, GUF, HH-3: COM, AGN, MAL, AAF, HH-4: COM, AGN, MAL, AAF, SBG, PGM, GUF) were extracted using SDE and their antioxidant and anti-inflammatory effects were measured by using DPPH radical and SLO, respectively. As a result, HH-2 showed moderate DPPH radical scavenging activity (68.24 %) and the strongest SLO inhibitory activity (83.96 %) at 100 ${\mu}g$/mL. Moreover, HH-2 of four different prescriptions significantly inhibited NO production on LPS-stimulated RAW 264.7 cells in a dose-dependent manner without considerable cell cytotoxicity at range of 2.0 ~ 50 ${\mu}g$/mL. Additionally, HH-2 also effectively suppressed the production of $PGE_2$ and IL-6, which are responsible for promoting the inflammatory process. Major volatile components of HH-2 were identified as eugenol, paeonol, butyl phthalide, ${\beta}$-eudesmol and butylidene dihydrophthalide by GC-MS analysis. Thus, these results suggest that HH-2 may be useful as a potential source of anti-inflammatory agents in herbal medicinal cosmetics.

In this study, we investigated the variation in free sugars, amino acids, antioxidant activity, and anti-inflammatory activity of Solanum nigrum Linne based on harvest time. Major amino acids identified by HPLC analysis were proline, histidine, and serine. The highest content of total amino acids were found in S. nigrum aerial parts and roots harvested on July 10th and August 10th. Four kinds of free sugars (fructose, glucose, sucrose, maltose) were detected in S. nigrum, and the free sugar content varied significantly with harvest time. The fructose content of S. nigrum decreased with as harvest time increased. The total polyphenol content of S. nigrum was highest in those harvested on August 30th. The antioxidant activity of ethanol extract from S. nigrum collected at different harvest times were measured by DPPH and ABTS radical scavenging assays. The anti-inflammatory activity of these extracts were assayed via nitric oxide suppression in C6 glioma cells with a lipopolysaccharide (LPS)-induced inflammatory response. The anti-inflammatory activity and antioxidant effects were the highest in the extract from S. nigrum collected on August 30th. Good correlations were observed between antioxidant and anti-inflammatory activities in ethanol extract of S. nigrum roots harvested on August 30th.
